So David, who has control, and what do they need to do?

Every time I've asked someone in the chain about what it takes to
sign the root, their part is done, it's others who aren't doing
their bits.

Perhaps I'm too much of an engineer.  Today there is a process for
IANA (ICANN?) to say "update the IP for from x
to y" and it makes it to someone who can run vi on the master file,
and they insert a new entry, and boom the root has it.

It seems to me if IANA (ICANN?) generates sigs, hands those same
records to the same person with vi access to the file and they add
them then boom, the root would have it.  Signature records are no
different than any other type of record in the root, and other
records have been updated in the past.

Since you already have the sigs on the web page why can't they be
sent to the guy with vi access the same as any other record change?
Please, let us know so people can go fix it.
